The name worgen inspires fear to the hearts and minds of the Horde and to some lesser extent, members of the Alliance.
Records indicate that the worgen, a race of lupine humanoids, existed for a time in Kalimdor. Other evidence also suggested that the Worgen were from a different world, that came through portals by Archmage Argual. In fact, more recent evidence suggested that their true origin might have a connection to the night elves and a secretive druidic order from Kalimdor's distant past. This proved to be correct as the curse originated from a druidic sect who followed Goldrinn, known as Druids of the Pack. They shapeshifted into the feral worgen and eventually lost their minds to its violent nature. The other Druids agreed that they must be locked away, and thus put them into eternal slumber deep beneath a tree... until the day Arugal and Velinde Starsong tampered with the Scythe of Elune. It was the night elves, after all, who created the curse in the first place. Obliged to help their newfound allies, they re-introduced them to the Alliance.
The worgen's first verified appearance in the Eastern Kingdoms has been traced back to the Third War, when the archmage Arugal utilized the wolf-beasts as a weapon against the Scourge. Arugal's weapons soon turned against him, however, as the curse of the worgen rapidly spread among the human population, transforming ordinary men and women into ravenous, feral creatures.
Arugal adopted many of the worgen as his own and retreated to the former mansion of Baron Silverlaine, the estate now known as Shadowfang Keep. The curse, however, was not contained. It persisted in the lands of Silverpine and extended even into the fabled walled nation of Gilneas, where the curse rapidly reached pandemic levels.
The citizens of Gilneas found themselves trapped, with no hope of escape. They retreated deeper within the isolated domain, and there they survived, fearful of the savage presence that lurked just outside the barricades.
Tensions among the displaced citizens escalated over time, resulting in a civil war that now threatens to destabilize the embattled nation even more.
There are those among the Gilneans, however, who cling to hope. Many believe that a cure for the worgen curse may exist, although others have nearly given up, fearful that if the barricades should fall, their humanity will be lost forever.[1]
Worgen are the new playable Alliance race introduced in World of Warcraft: Cataclysm and can choose a class from death knight, druid, warrior, hunter, mage, priest, rogue, or warlock.
Outside of combat, worgen can appear in either their human form or their worgen form. They immediately turn into their worgen form when entering combat or activating their Darkflight racial ability.
Recently the Greymane Wall was shattered by the Cataclysm. Setting their sights on the now-vulnerable country of Gilneas, the vile Forsaken have started an invasion of the kingdom. In their hour of greatest need, the worgen of Gilneas called out for their old allies' aid. The Gilneans are now back in the Alliance, and with their new allies by their side they aren't giving up their home without a fight.
Lore reasons for classes
Druid
There is sufficient proof and reason to believe that the practices of primitive druidism or "the old ways" were once alive and well within or around Gilnean society before the sealing of the Wall. It is likely that that the people of Gilneas would have once practiced or acknowledged (in varying degrees) the traditions and reverences of nature worship.
In time though (before the Greymane Wall was erected) the followers of the Holy Light must have spread their teachings to Gilneas and succeeded in converting many of its people, causing druidism to slowly fade into the past and become mostly forgotten.
When starting a Worgen Druid the quest text from Celestine of the Harvest does seem to support these assumptions. During Hallow's End the Faction Commoners and Celestine of the Harvest also have quest text supporting these assumptions, connecting Gilneas, druidism, and the traditions of Hallow's End.
That said, the Night Elves have taken great interest in the Worgen and are readily teaching them more about druidism, helping them to understand other areas of the path. It seems that this is the kaldorei's attempt at redemption in the eyes of their allies as they are partially responsible for the Worgen curse reaching them... They feel they owe it to the Worgen to explain and teach the magic that can lead to their salvation, druidism.
Mage, warlock, priest, rogue, warrior and hunter
The worgen have retained the skills they had as human citizens and choose to continue using them after their transformation.
Death knights
Worgen death knights are former slaves of Arugal. These former Gilnean citizens of Pyrewood Village managed to escape the wizard's control only to fall prey to The Lich King. During the Death Knight starting quests, you learn how Worgen death knights came to be.
When you start a worgen Death Knight, you start with their racial abilities, including [Two Forms].
Lord Harford says: Come to finish the job, have you?
Lord Harford says: You'll look me in the eyes when...
Lord Harford says: <Name>?
Lord Harford says: <Name>, I'd recognize that face anywhere... What... What have they done to you, <name>?
Lord Harford says says: You don't remember me? We were both servants of Arugal back in Silverpine Forest. We put up with his merciless torture for ages. It was you who saved me on that fateful night when we escaped Shadowfang Keep.
Lord Harford says: Without you I would have died. YOU! The most noble worgen I ever knew.
Lord Harford says: What have they done to you, <name>? How could this have happened?
Lord Harford says: Remember the worgen you once were, <brother/sister>! You were our savior! Fight this!
Lord Harford says: Listen to me <name>. You must fight against the Lich King's control. He is a monster that wants to see this world - our world - in ruin.
Lord Harford says: Don't let him use you to accomplish his goals. You were once a hero and you can be again.
Lord Harford says: Fight, damn you! Fight his control!
Knight Commander Plaguefist yells: What's going on in there? What's taking so long, <name>?
Lord Harford says: There... There's no more time for me. I'm done for. Finish me off, <name>. Do it or they'll kill us both. <Name>... Remember Gilneas, our beloved home. This world is worth saving.
Lord Harford says: Do it, <name>! Put me out of my misery!
The playable worgen are Gilneans. The speech should be pretty easy, as the people of Gilneas speak with a British accent and utilize similar phrases, such as "Get gabbing or get going." Some few (like Lieutenant "Foxy" Topper) also use Cockey dialect and slang. Worgen speech is the same in either form, though the worgen form has the addition of growls, howls, sniffs, barks, etc; it is important to know when to use these, as the vocalizations should follow a smooth presentation, rather than suddenly howling in another's face.

Trivia
Prior to the worgen's introduction, night elves were the only Alliance race shown to do flips when jumping.
The female worgen dance is Lady Gaga's Pokerface. The male's is the dance from My Love by Justin Timberlake.
Worgen are the only race that produce the proper sound effects when you use the '/sniff' emote.
Typing the '/roar' emote into the chat box will cause a worgen player to do an animation, and actually roar, where as other races will do nothing.
There is an irony between the worgen and tauren races when it comes to the development of their mounts. Tauren were not intended to have mounts originally, and were instead supposed to be given the "Plainsrunning" ability which would allow them to run at mounted speed. They were eventually given kodos as mounts. Worgen were supposed to have a mount, however its design failed to be finalized during the late stages of development prior to release and was removed, and in its place worgen were given the Running Wild ability, which is very similar to what the Plainsrunning ability was intended to be.
Blizzard announced that worgen horse mounts would eventually be added to the game in Patch 4.3,[4] but players were largely disappointed that the models were not distinctive from normal human horse mounts in almost any way and the large worgen character models look silly on the ill-sized horses.
The Forsaken fleet's destruction by the Cataclysm in the worgen starting zone might have been inspired by the Mongol invasion of Japan in 1271 to 1281, during which the majority of the Mongol's invading force were destroyed when an unexpected storm decimated the fleet of ships carrying them, along with most of their supplies, saving the Japanese, who were both inexperienced and outnumbered.
